* [MM-71101] Add ConfigStrings snapshot accessor ConfigStrings reads list settings such as DataSourceReplicas. It returns ok=false when the config section is absent or any element is redacted, so a redacted replica DSN cannot be read as a host name. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * [MM-71101] Add database health rules Ports the database checks from the health check script into a new rules/database package: replica sizing, Trace, MaxOpenConns, QueryTimeout, HA failover connection bursts (merged with the pooler check), PostgreSQL version, pool saturation, unused replicas, IP-literal DSN hosts, replica lag monitoring and MaxIdleConns above MaxOpenConns. Rules that read DSNs only report derived facts; no DSN or host leaves the rule. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * [MM-71101] Update health packet fixtures and expectations for database rules The fixture configs gain the SqlSettings and ElasticsearchSettings keys a real packet carries, and the HA fixture raises MaxOpenConns to 200 so the golden set covers DB_HA_FAILOVER_STORM_RISK offline. The mmctl test packet gains the database diagnostics and stats the rules read, and the parity test expects DB_QUERY_TIMEOUT_HIGH from the test store's 60 s timeout. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * [MM-71101] Parse every DSN host and skip non-Postgres version checks hostsFromDSN replaces hostFromDSN and returns every host a DSN names: comma-separated host lists, host/hostaddr query parameters in URL form, and hostaddr in keyword form. DB_CONNECTION_IS_IP fires when any host is an IP; the failover rule treats a DSN as pooled when any host is a pooler. DB_POSTGRES_UNSUPPORTED returns unknown when the diagnostics report a database type other than Postgres, so older MySQL packets no longer raise a Postgres version warning. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Raise DB_NO_SEARCH_REPLICA threshold to 2M posts Matches the documented point where database search starts to degrade. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Remove DB_CONNECTION_IS_IP rule An IP address in a DSN is correct for loopback, floating VIPs and k8s services, and harmless on single-node installs, so the rule was mostly noise. hostsFromDSN stays for the failover rule's pooler check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Remove DB_REPLICA_LAG_UNMONITORED rule ReplicaLagSettings only feeds Prometheus gauges, and managed databases already report replica lag, so the rule was an observability nudge with nothing misconfigured. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Simplify database health rules and tighten failover storm risk - Drop Snapshot.ConfigStrings; its only caller now just counts entries. - Parse only URL-form DSNs: sanitized config redacts every other form. - DB_HA_FAILOVER_STORM_RISK counts only primary pools in the burst and treats loopback hosts and Unix sockets as a per-node pooler. - DB_POOL_SATURATED checks the unlimited-pool gate before reading diagnostics. - Share the minimum PostgreSQL version via model so sqlstore and DB_POSTGRES_UNSUPPORTED cannot drift apart. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Fire DB_HA_FAILOVER_STORM_RISK when any host bypasses the pooler The driver tries a host list in order, so a direct host in the list can take the full reconnection burst. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Skip DB_NO_SEARCH_REPLICA when database search is disabled DB_POSTGRES_UNSUPPORTED now also reports unknown when the database type is missing. * Base DB_REPLICA_UNUSED on replica online state Open connection counts drop to zero on idle replica pools, so the rule now reads a new replicas_online support packet diagnostic. --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
